From the depths of the sea, where darkness meets vastness, emerges Leviathan: an unyielding force of speed and power. In a world where the arcane and the agile intertwine, a loop forged in Python takes its dance. Leviathan, master of the journey, governs events with a steady hand—an ultra-fast event loop that deploys its bastion in asyncio, powered by the artistry of Zig. Between promises and futures, its path is clear: to rule swiftly where code is prepared.

• Ultra-fast speed: Thanks to low-level optimizations enabled by Zig.
• Full asyncio compatibility: A drop-in replacement for the default event loop.
• Efficient design: Focused on maximizing performance and minimizing latency.
• Simplicity: Easy integration with existing Python projects.
• Robust Safety: Carefully engineered for critical systems with advanced error recovery and graceful degradation mechanisms.

• Python >= 3.13
• Zig >= 0.14.0 (for development or contributions)
• Linux >= 5.11

To install Leviathan, just execute:

python setup.py install

import leviathan
import asyncio
async def main():
    print("Hello from Leviathan!")
    await asyncio.sleep(1)
    print("Goodbye from Leviathan!")
leviathan.run(main())

Leviathan stands out for its speed and performance. Here is a preliminary chart illustrating its superiority over other event loops:
